FOUNTAIN PEN'.

Application filed .Tilly 31, 1922. Serial No. 578,621.

T0 all whom t may concern:

Be it known that l, Mounts H. Simian, a citizen of the United States, and a resident of New York city, inthe countyandfState of New York, have invented certain new and useful improvements in a Fountain Pen, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to increase the available quantity of marking fluid carried by the pen; to facilitate cleaning of the pen; to vary the density of the marking fiuid; and to simplify and cheapen the construction of the pen.

Drawings.

Figure 1 is a sectional side elevation of a fountain pen constructed and arranged in accordance with the present invention.

Figure 2 is av section taken on the line 2 2 in Figure 1.

Figure 3 is a section taken on the line 3-3 in Figure 1.

Figure 4 is a side view of the container for concentrated Huid.

Figure 5 is a side view of the closure cap valve.

Figure 6 is a side view of a valve employed in the construction of said pen.

Description.

The herein disclosed pen is designed to employ a charge of initially clear water and a charge of heavy concentrated coloring fluid. The two charges are loaded into the pen separately. In service it is calculated that the supply or charge of the concentrated coloring fluid -will be sufficient for many charges of the clear water thus prolonging the length o-f utility of the pen as a marking instrument.

To this end the pen is provided with a water reservoir 11 and a concentrated color liquid 12.

As seen best in Fig. 1 of the drawings the reservoir 11 is operatively connected with the reservoir 12 through a passage 13 in the plug extension 14 of the barrel 15. the hollow of which forms the said reservoir for color liquid.

The passage 13 is normally closed by a pin valve 16, the conical end of which enters the passage 13 and forms a seat at the inner end thereof. If found necessary a ground joint may be employed at this point to prvent the. passage of the liquid from the reservoir 12 to the reservoir 11. The pinvalve 16 is normally held inoperative position by a .screwplug 17. rlhe screw plug' 17 has a vneedle valve 16 a knurled head 19 is provided.

To seal the reservoir 12 when the pin valve 16 is seated in closure relation to the passage 13 a rubber gasket 20 is provided. The gasket 20 covers the air-bleed perforations 21 with which the plug 17 is provided. By lifting the gasket 20 from the perforations 21, air enters the reservoir 12 to permit the fluid to pass from the said reservoir to the reservoir 11. When suflicient fluid is passed to color the water in the reservoir 11, the valvev 16 is rotated until the conical end thereof closes the passage 13, terminating the flow of the concentrated liquid. Usually the barrel 22 having the chamber 11 is permanently attached to the chamber 15, a screw-threaded connection being made therewith and with the plug 14 thereof as seen best in Fig. 1 of the drawings.

The pen section 23 is connected with the barrel in the manner similar to that employed in many of the pens of usual construction.

When it is desired to charge the reservoir 11 with water the pen section 23 is removed and water is poured into the reservoir. When the reservoir 11 is filled, the pen section is reinstated in its service position and the valve 16 is lifted slightly to permit a sufficient quantity of the concentrated liquid in the reservoir 12 to pass through the perforation 13 into the reservoir 11 to miX with the water supplied thereto. After closing the valve 16, the pen is shaken-so that the water in the reservoir 11 becomes thoroughly and evenly colored.

sion being centrally perforated to `form a communicating passage between the chambers in said barrels; an elongated pin valve for closing said passage, said pin valve having a screw-threaded section for advancing and receding said valve; and closure means for the end of one of said-barrels for operatively engaging said screw-threaded secf tion, said closure means embodying a screwthreaded plug centrally perforated in correspondence with the screw-threaded section of said valve and having an air-duct formed therein.

2. A fountain pen as characterized comprising a plurality of chambered barrels; means for permanently connecting said barrels, said means embodying a screw-threaded extension on one barrel v-and a correspondingly tapped end on the other, said extension being centrally perforated to form a communicating passage between the chambers in said barrels; an elongated pin valve for closing said passage, said pin valve having a screw-threaded section for advancing and receding said valve; closure means for the end of one of said barrels for operatively engaging said screw-threaded section; said closure means having an air duct therein Jfor admission of air to the interior of said barrel, and means for removably covering said air duct.
